Which is better for a child's first tumbler?

The National Geographic kit. It includes the rocks, grit and jewelry fastenings, has a timer, and costs $58.00 to $60.00. The Lortone is a better machine but needs grit bought separately and adult supervision.

The Lortone 3A. Its continuous-duty motor is rated to run 24 hours a day for years, and owners report long service. The National Geographic is a hobby unit backed by a 2-year warranty.

Is the Lortone worth the extra money?

Yes if you tumble often. It holds about 3 lb against 0.5 kg and runs continuously. For occasional family use, the National Geographic kit does the job for less than half the price.

How long does a batch take?

The Lortone 3A takes about 4 to 6 weeks for a full polish. National Geographic does not state a batch time, but the 1-to-7-day timer suggests shorter stages with coarser grit.

Do I need to buy grit for the Lortone?

Yes. The Lortone 3A ships with the tumbler and a 21-page tumbling booklet but no abrasives. The National Geographic kit includes four grit grades.

Can the Lortone handle hard rocks like quartz?

Yes. The rotary action suits hard minerals such as quartz. The National Geographic kit is aimed at the softer gemstone mix it ships with.
